Question

Consider the grammar G below in the input alphabet {num, *, /, -}, with non-terminal leading S' in rule 1.

  1. S'→S$
  2. S→E - F
  3. F→E * E
  4. E→num
  5. E→num / num

a) Build the G grammar automaton. Is this grammar LR(0)?

b) If G is not LR(0), list the items present in the DFA state where the conflict occurs.

c) Is this grammar SLR?

d) If G is SLR, write the non-terminal follow that resolves the LR(0) conflict. (Separate the items in the set with “:”. Ex: a:b )
